3Dputty SF Bio, our light curing bio-based sacrificial easy breakable Soft & Flexible putty

Product description

3Dputty SF Bio is a light curing bio-based sacrificial easy breakable soft & flexible putty curable with UV & visible light in seconds.

Its usage is ideal as easy breakable demolding filler for filling the gap between 3D printed molds and injector flasks. It is a safe and fast light curing bio based soft and flexible putty made from renewable sources, which before exposure to UV / visible light can be modelled by hand or with a spatula, and after being shaped or modelled it can be hardened with a normal UV / visible light in seconds to become an easy breakable soft and flexible filler for easy demolding.

Application framework
